CHARELS SMITH DENNEY, OF TOMS CREEK, VIRGINIA.

ANGI-IORING MEANS FOR MOVABLE MACHINERY.

To all whom it may concern Be it known that T, CI-IARELS S. DENNEY, a citizen of the United States, residing at Toms Creek, in the county of lVise and Potato of Virginia, have invented certain new and useful lmprovements in Anchoring Means for Movable Machinery, of which the following is a specification, reference being had to the accompanying drawings.

This invention comprehends certain new and useful improvements in anchoring means for coal or ice cutting machines and other movable machinery.

The primary object of this invention to provide anchoring means which may be readily positioned and connected with the machinery to anchor the latter in the desired position during operation thereof.

Another object is to provide anchoring means of this nature which will be of simple and durable construction and which may be readily secured to a stationary support to properly anchor the machinery.

A further object is to provide a device of this character which, after being secured in position, may be readily turned in any direc tion and which will securely anchor the machinery against movement during operation of said machinery.

A still further object is to construct anchoring means of this nature, the rotatable lower portion of which pivotally carries a shoe having an anchoring point for engagement in the ground or other surface and an upwardly directed portion for holding one end of a. cable or the like connected with the machinery to be anchored.

A still further object is to generally improve and simplify the construction of de' vices of this character and increase the elliciency thereof, thereby rendering the anchoring means more practical and commerci ally desirable.

lVith the above and other objects in view, this invention consists in certain novel details of construction, combination and an rangement of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawing, in which Figure 1, is a side elevational view of my anchoring means in position and connected with a cable extending from movable machinery. Fig. 2, is a front elevational view thereof, parts being shown in section. Fig. 3 is a detail perspective view of the anchoring shoe.

Serial No. 743,602.

Referring more particularly to the drawings, wherein similar reference characters designate corresponding parts throughout, the numeral 1 designates the anchor rod, which is preferably secured in a wall, or other suitable support, it being understood that a suitable opening 2 is provided in the wall or other support to receive the anchor rod 1. One end of the anchor rod 1 projects downwardly from the support within which it is secured, and the collar 3 is secured upon said rod near its free end, a circuinfcrential groove '-1 being provided in the rod 1 to receive the collar 3 and prevent longitudinal movement of the latter upon said rod. The collar 3 is provided with the parallel (le 'iending ends 5 with the pivot bolt 6 extending transversely therethrough. The suspending rod 7 has its reduced upper end 8 secured upon the pivot bolt 6 between the arms 5 of the collar 3, while the U-shsqaed member 9 is swivelly mounted upon the lower end of the suspending rod 7, at the bight portion of said U-shaped member. as shown at 10.

The pivot pin 11 is secured through the lower ends of the legs of the U-shaped member 9 and upon this pivot pin 11 is mounted the anchoring shoe 12. The shoe 12 may be constructed in any suitable manner, but I have shown the same as being formed. in one piece bent around the pivot pin 11 at its central portion 13 and having one end bent downwardly at an angle, as shown at 14, with a sharp beveled edge 15 for engagement with the floor of a coal mine compartment when the device is employed to anchor a coal cutting machine. It will be evident, however, that the edge 15 will bite into the ground or other surface when the device is employed for anchoring other machinery. The opposite end of the shoe 12 is bent upwardly and rearwardly, as shown at 16, and provided with the slot 17 to receive one end of a cable 18, or other connecting means eX- tending from the movable machinery. It will be understood that the ends 1a and 16 are bent in opposite directions at the points 1 1 and 16, respectively, and between the points 14 and 16 and the central portion. 13 of the member 12, the shoe extends longitudinally, and the upper portion 16 is parallel with and rests upon the lower portion 1 1.

It will be understood that the opening 2 is formed in the stationary support the horizontal position.

proper distance above the floor or other surface with which the edge 15 of the shoe 12 is to be engaged. It will also be apparent that the suspending rod 7 may be swung to proper position upon the pivot 6 beneath the anchor rod 1 or, if desired, the sleeve 3 may be rotated upon the rod 1 to swing the sus pending rod 7 to a horizontal position if desired, or any position between a vertical and It will also be seen that the U-shaped member 9 may be freely rotated upon the lower end of the suspending rod 7 without changing the position of the latter to properly place the shoe 12 for receiving the cable 18 and causing the lower beveled edge 15 of said shoe to bite into the surface with which it is engaged. It is evident that the strain upon the cable 18 will cause the lower beveled edge 15 of the shoe 12 to securely bite into the surface with which it is engaged, thus securely anchoring the machine with which the cable is connected and eliminating all danger of the anchoring means being withdrawn from its.

position, as all strain upon the cable 18, forcing the edge 15 into the surface, will be received by the pivot pin 11, causing a slight upward movement of the U-shaped member 9, suspending rod 7, collar 3, and free end of the anchor rod 1, thus equally distributing the strain to the various parts of the device and causing the anchor rod 1 to bind against the walls of the opening 2.

It will be apparent to all those familiar with such devices, that any number of the same may be employed for properly anchoring a coal cutting machine or the like, and that the shoes 12 may be turned at any angles desired and connected by cables or the like to the drums or other parts of the machinery, as occasion may require.

While I have shown the preferred embodiment of my invention, it will be understood that I do not wish to be limited to this specific construction, as minor changes in the details of construction may be made within the scope of the appended claims without departing from the spirit of my invention.

What is claimed is 1. Anchoring means comprising a shoe having a biting edge and a cable receiving edge, a rotatable member pivotally connected to the shoe, means for suspending the rotatable member above the shoe, and an anchor rod connected with the suspending means.

2. Anchoring means for machinery, comprising an anchor rod adapted to be secured in a stationary support, a suspending rod pivotally and rotatably connected to the anchor rod, a U-shaped member carried by the suspending rod and having a pivot pin secured through its legs, an anchoring shoe engaged at its central portion around the pivot pin, one end of said shoe being directed downwardly and having a beveled biting edge, the opposite end of the shoe being bent upwardly and rearwardly and provided with a downwardly extending slot opening in the upper edge thereof, and a cable secured in said slot.

3. Anchoring means for machinery comprising an anchor rod adapted to be secured in a stationary support, a suspending rod, means for pivotally and rotatably connecting the suspending rod to one end of the anchor rod, a U-shaped member carried by the suspending rod and having a pivot pin secured through its legs, an anchor shoe engaged around the pivot pin and having a beveled biting edge, and acable detachably connected with the shoe.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
